Jeep Issues

I have a 2000 Wrangler Sport with about 130,000 miles on it. Recently I have been having a few issues with it. This is my first vehicle that is not a front wheel drive.
1. When stepping on the gas there sometimes id a delay tachometer goes up but takes a while for it to get going.
2. There also is a wine when I let off the accelerator. As soon as I step back on the accelerator it seems to go away. I only noticed it after I had to change the positive battery cable with a much longer multiple use one from the local auto store. Could it be due to feedback?
Please give me any thoughts.
Thank you,

Automatic or manual transmission? Issue number one sounds as though either the clutch or transmission is slipping. Is that what you're saying? Issue number 2: whining like electrical noise? Where is it coming through? Or is it whining like mechanical noise?

It is a Automatic transmission. The noise seems to be comming from the engine bay.

On the first issue, I take it your describing that after you shift into drive there is a delay before the transmission will drop into gear? If this is the case do not race the engine causing the tranny to slam into gear, your just causing further problems.

Check the level and condition of the transmission fluid. (Vehicle running, and engine & trans fully warmed up, parked on level surface) If its low, add some asap. (Has it ever been changed?) Is it nice and red, or is it brownish, and have a "burnt smell"? The latter will require a full fluid and filter change, not just adding fluid - and no guarantee that a fluid & filter change will correct the slipping issue. It all depends on how long its been let go.

For #1 above..how long in seconds is "takes a while"

#2.) you mention the battery cable. Are you hearing the sound with the radio turned on? If so, it could possibly be feedback as you mentioned. If the radio is off, then it is not that. A whine can be hard to diagnose over the internet. Could be about any engine accessory or any part of the spinning drivetrain, that increases and decreases in speed.

I checked the transmission level. It is at the min level. I will add a touch more and see if that helps. I got the Jeep in April. I don't know if was changed prior to me getting it. The noise happens with radio on or off. Only happens till it heats up.

So I topped off the transmission fluid, and the hesitation stopped. Thank you! Fluid looked fine smelled ok but I am going take it in for a flush in the near future. Still having a noise when I let off the gas. Usually only happens till it gets warmed up (5 to 10 mins)

Have you checked your rear diff fluid yet? Typically if THAT is whining it's a constant thing...but stranger things have happened.

Honestly, one of the best things you can do with any vehicle, especially AWD/4WD is check (but even better CHANGE) all your running gear fluids. Make sure when you're doing this that the transfer case and front diff get done too; just because you're not in 4WD all the time doesn't mean the hardware doesn't move.

Keeping everything lubed up (don't forget your linkages too) will always pay off.
